COP- WINDING MACHINERY.

SPECIFICATION forming part of Letters Patent No. 24.2, 718, dated June'7, 1881.

Application filed October 21, 1880.

To all whom it may concern Be it known that we, WILLIAM WALTON UR UHART,JosEPnLINnsAY', and ROBERT ALLAN, subjects of. the Queen of GreatBritain and Ireland, all residing at Dundee, in the county of Forfar,Scotland, have invented a certain Improvement in Oop-Windin g Machinery,(for which we obtained a patent in Great Britain, No. 264, dated 22dJanuary, 187 9,) of which the following is a specification.

In our improved machinery the winding-spindles are short and have nomovement in the direction of their length, either while winding or whenihecops are being removed. The ordi nary conical formin g-cups areemployed to give the required compactness or firmess to the cop as it isbeing wound, the degree of firmness or hardness being regulated bypressure ap plied eudwise to the cop, or downward when the cops arewound in a vertical position, the cops receding or rising from the cupsagainst the pressure, as they are gradually formed by the windingoperation. Each cup is a sepa rate loose piece, being held by means oftrunnions formed on it, so that it can adjust itself to act equally onall sides of the cop, and the part carrying it is movable by means of ahandle. The winding-spindles are driven by means of ordinarybevel-wheels, and each has an improved clutch fitted with renewableengaging-pins, of steel.

feature of our improved machinery. Each spindle projects only a shortdistance through the cup, the part of the spindle on which the yarn iswound being made with three or more flat sides andslightly tapered, withthe point rounded, and as the cop grows upward or from the cup, inconsequence of the winding action continually adding conical layers ofyarn to the lowerend within the cup,the upper part. of the cop graduallyleaves the spindle, and when the desired length of cop has been formedthe spindle end projects onlyinto the conical end of it, and the cop canconsequently be removed with extreme facility. The upper or outer end ofthe cop is pressed uponand steadied by a small center or ball,arrangedto move in a line coincident with the axis of the winding-spindle. Thepart holding the outer center or ball The shortness of the winding-spindlesis a special and advantageous (No model.) Patented in EnglandJanuary 22, 1879.

means of a detecter-lever when the yarn breaks or fails.

Figs.10 and 11 are aplan and a front elevation of the cup. Figs. 12, 13, and 14 are a plan,a side elevation, and a front elevation of the detector-lever.- Figs. 15and 16 are a plan and a side elevation of a catch-lever connected withthe clutch details. Figs. 17 and 18 are a plan and a side elevation ofthe clutch-lever, and Figs. 19 and 20 are a sectional plan and a sideelevation, showing the clutch. 1

The main framing of the machine consists of transverse vertical framesor standards 21,

placed at the ends and at intermediate points,

and connected by four horizontal rails, an upper one, 22, and a lowerone, 23, extending along each side. Most of the details appertaining toeach spindleare carried upon or fitted in connection with a verticalframe-plate, 24, (seen bestin Fig. 2,) bolted to the upper and lowerrails, 22 23, each such frame-plate 24. being made with a long slot, 25,in which the balllever 26 and the cup -lever 27 work, and with shortslots 28 29 for the fulcrum end-s of the ball and cup lovers of theopposite side, the corresponding frame-plate, 24,- onthe opposite sidehaving similar slots for the fulcrum ends of the ball-lever 26 andcup-lever 27 of 5 the side that is being described. Each winding-spindle30 is short and has no movement in the direction of its length, beingheld in upper and lower bearings, 31 32, formed on the frame-plate 24.An ordinary conical forming- ICIO cup, 33, is employed to give therequired compactness or firmness to the cop as it is being formed; butthis cup is loose, being formed with trunnions, which rest in notches 34in the forked cup-lever 27 so that it can adjust itself to the cop andequalize the pressure on all sides. The cup-lever 27, which has one sideof its forked part extended to form a handle, 35, is passed through theslot in the frame-plate 24 and extends across the machine to a slot, 29,in the frame-plate at the other side, the bottom of the latter slotserving as a fulcrum to the lever. A stud or small projection, 36, isformed on one side of the cuplever 27, and, bearing against the face ofthe frame-plate 24, prevents the lever from being pushed too far inwardthrough the slot 25; and the cup-lever 27 is also formed with anupwardly-projecting part, 37, which serves as a rest for the ball -lever26 when in its lowest position.

The row of winding-spindles 30 at each side of the machine is directlyover a horizontal driving-shaft, 38, having on it bevel-wheels 39, whichgear each with a bevel-pinion, 40, loose on the lower end of awinding-spindle, 30, the pinion driving the spindle through a specialclutch, hereinafter described. It is one advantage of our improvedarrangement that the bevel wheels 39 and pinions 40 do not require to beof the skewed kind, as the spindles 30.

have no vertical or end wise movement and can be placed in the plane ofthe driving-shaft. The feature is not absolutely novel in itself, but weare enabled to adopt it without inconveniences experienced with otherarrangements. One part of the clutch is a renewable pin, 41, which isfixed by a pinching-screw in a boss formed for it on the bevel-pinion40, a similar boss being formed at a diametrically-opposite point topreserve the balance. The other part of the clutch isa two-collaredtube, 42, fitted to slide on the spindle 30, but engaging with it by apin and groove,and provided with a renewable pin, 43, which is fixed bya pinclr ing-screw, and which engages with the pin 41 of thebevel-pinion 40 when the tube is moved between the collars of theclutch, and this clutch-lever 44 has jointed to itsother end a bar, 45,which extends down vertically and is jointed to a treadle or foot-lever,46, below. The parts are made of such weights that they raise the clutch42 out of gear when the clutchlever 44 is not held by means of acatch-projection, 47, formed 011 one side of it. When, by action on thetreadle 46, the inner end of the cluch-lever 44 is raised itscatch-projection 47 engages with a latch-catch, 48, formed on acatchlever, 49, centered on a backwardlyprojecting part, 50, of theframe-plate 24, this catch-lever 49 having the weights of its parts soproportioned that the catch 48 enters under thecatch 47 of theclutch-lever when this rises high enough. A shoulder formed on the barprevents it from being raised too high by encountering the bottom rail,23.

Each spindle 30 extends upward only to about the top of the cup 33, andthe part within the cup is made with flat sides and slightly tapered,the point or upper en d being rounded. hen the cop is completed thespindle end projects only into the conical part of it, and the cop canbe very easily lifted off the spindle by raising the cup-lever 27 bymeans of its handle 35. The upper end of the cop is pressed upon andsteadied by a small center or ball, 5], arranged to move in a linecoincident with the continued axis of the winding-spindle 30. This ball51 is formed on a downwardly-projecting part of the front end of theball-lever 26, which lever works in the slot 25 of the framing-plate 24,its other end being entered into a slot like the slot 28, but in theframeplate 24 at the other side of the machine.

On one side of the ball-lever 26 there are formed two studs, 52, whichguide the lever by sliding one on the outside and the other on theinside of the frame-plate 24, at one edge of the slot 25,this slothaving a widened part at its top to allow of the entrance of theinnermost of the two studs 52. A curved rib, 53, (seen at the ri ght-hand side of Fig. 1,) is formed at the back of the frame-plate 24, atthe part where the innermost stud, 52, moves, and the curvature of thisrib 53 is such as to cause the ball 51 to move with sufficient accuracyin a line coincident with the continued axis of the windiugaspindle. Onthe other side of the balllevcr 26 there is centered a handle-catch, 54,which can engage with any one of a series of ratchet-teeth, 55, formedon the frameplate 24, along one side of the slot 25, and this catchserves for supporting the ball-lever 26 in any of its positions, beingheld clear of the ratchetteeth by hand when lowering the lever. Theball-lever 26 may be inade of sufficient weight for pressing the copinto the cup 33, or a weight may be applied to it for that purpose.

When the desired length of cop has been formed the ball-lever 26, inrising, encounters a clamp or stop, 56, on the stop -rod 57, this .rodordinarily resting by a hook formed on its upper end, which passesthrough a slotl in thetop rail, 22. The stop 56 can be clamlped indifl'erent positions on the rod 57, so as to be reached later or soonerby the ball lever 26, accordingly as a longer or shorter cop is desired.The numerals shown on the bar 57 in Fig. 8, represent lengths of cop ininches. The rod 57 extends downward past the catch-lever 49, and it hasformed on its inner edge ashoulder or incline, 58, which, when the rodis liftedby the ball lever 26, acts on a cranked arm, 59, formed on thecatch-lever 49, and makes that lever let go the clutch-lever 44, whichthereupon disen gages the clutch and stops the wind ing action.

The yarn may be drawn off either reels or bobbins, but is shown as beingdrawn off bobbins 60, to which a drag is applied bymeans of a weightedspring-lever blade, 61, of thin metal, which bears on the yarn itself onthe bobbin, its action on full and empty bobbins being in consequencemore uniform than when pressure is applied to the bobbin. From thebobbin the yarn passes to a pulley or guide, 62, on the outer end of alight detecter-lever, 63, and thence to the finger of the traverse-guidelever 64, which finger works close to the slot in the side of the cup 33in the usual way. The detecter-lever 63 consists of a stout wire fixedin a peculiar boss or center, 65, Figs. 12,

13, 14, centered on a horizontal pin. This boss 65 is formed with onetoe, 66, which bears against a blade-spring, 67, fixed to the frameplate24, and with a second toe, 68, which extends under an arm, 69, formed onthe catchlever 49. The strain of the yarn holds up the lever 63, and thespring 67 tends to equalize the tension; but when the yarn breaks orfails the lever 63 falls, and its toe 68 then trips the catch-lever 49,and thereby causes the disengagement of the clutch and the stoppage ofthe winding action.

The traverse-guide levers 64 are adjustably fixed on horizontal shafts70, which shafts are made to rock by mechanism of the kind usuallyapplied for that purpose. Each guidelever 64 is a stout wire fixed inone of a pair of half-bosses, 71, bolted together on the shaft. Theshaft 70 is plain throughout, and the bosses 71 can be set in anyposition along it, and also in any position round it, so that each lever64 can be independently adjusted with accuracy to suit the spindle 30and cup 33, in connection with which it works.
